The ".5" is there so the bet cannot land on the line. Football scores are whole numbers, so 2.5 is just a way of saying "three or more". Over 2.5 wins on 3-0, 2-1, 2-2, 4-1 and anything higher. It loses on 0-0, 1-0, 1-1 and 2-0.
Under 2.5 is the other side of the same line. That one wins on zero, one or two goals.
Why the line is so common
Three goals is a natural place to split a football match. A lot of leagues land over 2.5 somewhere around half the time, which is why the price often sits near evens and why the market gets so much attention. It is also why a price near evens is not automatically interesting. If a league only goes over in 45% of games, evens is a short price, not a fair one.
The same idea shows up on other lines. Over 1.5 is two or more goals. Over 3.5 is four or more. Each one is just a different cut of the same match.
What I look at before the price
A team that scores a lot and concedes a lot is the obvious place to start, but the league matters as much as the fixture. Some competitions live around 3 goals a game. Others spend the season nearer 2. The table below is the current season, every league we track, sorted by how often games go over 2.5. It is not a shortlist of the famous leagues, so the top is often a youth or women's competition. That is still a real rate. It is just not the Premier League.

That is a league average, not a prediction for Saturday. A tight game in a high-scoring league can still finish 1-0. I use the table to see whether 2.5 is a normal result in that competition, then look at the two teams.
If you want the fixture list rather than the definition, the over 2.5 goals page ranks upcoming matches by our model probability. Both teams to score is a different bet: 2-0 wins over 2.5 and loses BTTS, and 1-1 does the opposite.
FAQ
Does 2-2 win over 2.5 goals?
Yes. 2-2 is four goals, and four is over 2.5. The scoreline does not matter, only the total.
Is over 2.5 the same as both teams to score?
No. Over 2.5 only cares how many goals are scored. Both teams to score only cares that each side scores at least one. 3-0 wins the first and loses the second.

Both teams to score is the other common goals market. Expected goals is a better read on how many chances a team created than the raw score. If the price on over 2.5 is longer than you think it should be, that is the value bet question.
